Every rider has a story about an agitated arthropod invading his or her personal space. Such tales are amusing, but riders who are sensitive to insect venom can end up in serious trouble. Some experience an allergic or anaphylactic reaction to the sting, sometimes in very short order. See your doctor for a test if you’re not sure. Reactions vary by insect species, and the location of the sting can increase the severity of the problem. Symptoms of a potentially life-threatening allergic reaction can include feelings of anxiety, disorientation, difficulty breathing, swelling of the throat or airway, hoarse/thick speech, nausea, vomiting, hives and chest pain.
